As an old skool minesweeper, I really enjoyed the idea, I think it's got a lot of potential.
I have noticed some performance issues playing from the browser:
- The game freezes the first time I drill, not sure if it's the world generating right there, or loading the sound resource, but the lag is noticeable.
- After some restarts, the game becomes very laggy and requires reloading the page. It looks like memory buildup.
